OpenSLP as used in VMware ESXi (7.0 before ESXi_7.0.1-0.0.16850804, 6.7 before ESXi670-202010401-SG, 6.5 before ESXi650-202010401-SG) has a use-after-free issue. A malicious actor residing in the management network who has access to port 427 on an ESXi machine may be able to trigger a use-after-free in the OpenSLP service resulting in remote code execution.

VMware ESXi contains an authentication bypass vulnerability. A malicious actor with sufficient Active Directory (AD) permissions can gain full access to an ESXi host that was previously configured to use AD for user management https://blogs.vmware.com/vsphere/2012/09/joining-vsphere-hosts-to-active-directory.html by re-creating the configured AD group ('ESXi Admins' by default) after it was deleted from AD.

VMware ESXi contains a memory corruption vulnerability that exists in the way it handles a network socket. A malicious actor with local access to ESXi may exploit this issue to corrupt memory leading to an escape of the ESXi sandbox.

GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution, aka "ShellShock." NOTE: the original fix for this issue was incorrect; CVE-2014-7169 has been assigned to cover the vulnerability that is still present after the incorrect fix.

VMware ESXi contains a heap-overflow vulnerability. A malicious local actor with restricted privileges within a sandbox process may exploit this issue to achieve a partial information disclosure.

OpenSLP as used in ESXi and the Horizon DaaS appliances has a heap overwrite issue. VMware has evaluated the severity of this issue to be in the Critical severity range with a maximum CVSSv3 base score of 9.8.

Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.

VMware ESXi contains an out-of-bounds read vulnerability. A malicious actor with local administrative privileges on a virtual machine with an existing snapshot may trigger an out-of-bounds read leading to a denial-of-service condition of the host.

The storage controllers on VMware ESXi, Workstation, and Fusion have out-of-bounds read/write vulnerability. A malicious actor with access to a virtual machine with storage controllers enabled may exploit this issue to create a denial of service condition or execute code on the hypervisor from a virtual machine in conjunction with other issues.

VMware ESXi, Workstation, and Fusion contain an information disclosure vulnerability in the UHCI USB controller. A malicious actor with administrative access to a virtual machine may be able to exploit this issue to leak memory from the vmx process.
